The High Temperature FluidLoc construction incorporates an internal seal that prevents process liquid migration through the inner cable layers, protecting electrical characteristics in harsh environment runs.\u003c\/p\u003e\n\u003cp\u003eDuring field commissioning, gap voltage validation requires verifying the baseline voltage at the Proximitor sensor output terminals against a nominal -10 VDC target at mechanical center span. Precise physical impedance matching suppresses signal phase shifts during high-amplitude rotor dynamics events and maintains optimal cross-talk suppression between closely spaced orthogonal probe channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 330854-040-24-CN extension cable be shortened or spliced during field routing?\u003c\/p\u003e\n\u003cp\u003eA: No. Shortening or splicing alters the physical inductance and capacitance of the matched coaxial path, which destroys sensor calibration, skews eddy-current probe scaling, and leads to incorrect gap voltage validation readings.\u003c\/p\u003e\n\u003cp\u003eQ: What function does the High Temperature FluidLoc cable option (Option 24) fulfill?\u003c\/p\u003e\n\u003cp\u003eA: The FluidLoc cable utilizes an internal barrier to prevent oil, water, and synthetic lubricants from wicking through the interior of the cable jacket into the terminal enclosure, preserving insulation resistance under thermal stress up to +200 deg C.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the FluidLoc cable jacket, end fittings, and coaxial contacts for physical damage, oil, or debris prior to installation.\u003c\/li\u003e\n\u003cli\u003eRoute the cable through metal conduit or dedicated wireways, maintaining a minimum static bend radius of 25.4 mm (1.0 in).\u003c\/li\u003e\n\u003cli\u003eMaintain at least 300 mm separation between the extension cable and high-voltage AC power lines or variable frequency drive (VFD) cabling to prevent inductive electrical noise.\u003c\/li\u003e\n\u003cli\u003eAlign the coaxial connectors, seat firmly until the locking mechanism engages, and slide a protective connector boot over the interface.\u003c\/li\u003e\n\u003cli\u003ePerform gap voltage validation across the Proximitor output terminals using a digital multimeter; confirm the reading matches the static reference target (typically -10 VDC).\u003c\/li\u003e\n\u003cli\u003eConnect the cable shield to instrument earth ground exclusively at the Proximitor enclosure end.
